The marine toad is generally found in the subtropical forests of Central and South America, where despite it's name, spends it's life entirely on the land. The marine toad has also been introduced to non-native regions as a form of pest control for crops.
Marine toads tend to be around 15 cm in length although much larger individuals have been recorded. Marine toads are known to have poison glands which ensure that it has toxic skin. This means that if another animal ate the marine toad, it's quite likely that it would lead to near, if not fatal, consequences.
Along with being used to control agricultural pests, the marine toad also has a variety of other uses to humans around the world. Traditionally, tribes people in South America would milk the toads for their toxin (called bufotoxin), which was then used as arrow poison. There are also suggestions that the toxins produced by the marine toad may have also been used as a narcotic by the local people.
As with numerous other toad species, the marine toad is a carnivorous animal, primarily surviving on a diet of insects. Due to their large size however, marine toads have also been known to hunt slightly bigger animals including rodents, reptiles, birds and even other amphibians.
Due to it's relatively small size, the marine toad is preyed upon by a number of different species within it's natural environment. Caimans, snakes, rats, eels, opossums and various birds of prey are all predators of the marine toad.
Like other amphibians, the marine toad undergoes the incredible transformation from a water-bound tadpole to a ground-dwelling adult in a matter of months. Like it's adult counterpart, the marine toad tadpoles are also highly toxic to any animal that eats them.
Today, the marine toad populations are thriving around the world due to the artificial introductions of the marine toad to many islands in the 1900s. Since then, the marine toad has become a pest in many of these countries as their ruthless nature poses a serious threat to native species.
